Cant Run Code Coverage In WinUI3

Open kitUIN opened this issue 10 months ago • 10 comments

I'm following the tutorial(create-winui-unit-test-project) and conducting unit tests, but I find that the code coverage is unavailable

vstest.console.exe bin\x64\Debug\net8.0-windows10.0.19041.0\win-x64\App1.build.appxrecipe /Logger:trx  /Settings:test.runsettings  /Diag:1.txt

test.runsettings

<RunSettings>
	<RunConfiguration>
		<DisableAppDomain>True</DisableAppDomain>
	</RunConfiguration>
	<DataCollectionRunSettings>

			<DataCollector friendlyName="Code Coverage"  >

@kitUIN Are you using Visual Studio Enterprise? Or Professional/Community edition?

Code coverage components are shipped only with Visual Studio Enterprise edition.

Please download Microsoft.TestPlatform and try vstest.console.exe from this package.

I copied all the files in the package to the vs folder and executed it, but it still gives me the original error.

Copying to VS folder will not work. Microsoft.TestPlatform nuget package and Microsoft Visual Studio installation folder are not the same. Microsoft Visual Studio required additional coverage components.

I tried this command from the nuget package and it generated coverage report correctly. Please try this out and do let me know if it works or not.

I tried this command from the nuget package and it generated coverage report correctly. Please try this out and do let me know if it works or not.我从 nuget 包中尝试了这个命令，它正确地生成了覆盖率报告。请尝试一下，如果成功请告诉我。

fhnaseer avatar May 22 '25 07:05 fhnaseer

You have to point the console to App1.build.appxrecipe to run via the uwp test runtime provider, if you use dll it will choose the desktop test runtime provider, which does not host the app correctly.

数据收集器“Code Coverage”消息: No code coverage data available. Profiler was not initialized.。

However, once the App1.build.appxrecipe is used, the above error will occur. I haven't found any solution for the time being It's normal (as in vs) if code coverage is not enabled, but I precisely need code coverage
